GPIB Controller
The GPIB‑RS485 is an IEEE 488 controller device for PCs with RS485 or RS422 ports. You can use this device to integrate an instrument into your system using GPIB. This device transforms a computer with an RS485 or RS422 serial port into a talker, listener, or controller on the GPIB bus. It can also interface RS485 and RS422 instruments and peripherals to the GPIB bus. It can implement the physical and electrical specifications of the IEEE 488, RS485, and RS422 standards, as well as interpret and execute high-level commands from the serial port, including serial‑to‑GPIB, and GPIB‑to‑serial protocol conversions. This device is IEEE 488.2 compatible. The device includes a license for the NI‑488.2 driver software, providing maximum reliability for connecting to third-party instruments with GPIB.
